“…In this study, we found that a high proportion of patients with severe MS have associated PAH. This prevalence was similar to those observed in other studies analysing the outcome of patients with PAH after PMV or surgical replacement [21][22][23]. Although most reports do not describe the percentage of patients with PAH, some registries with a larger number of patients showed mean or median PASP values similar to those of this study [19,24,25].…”

“…Most registries showed a decrease of MVA in the five-year follow-up period between 0.12 to 0.20 cm 2 , related to an increase in the rate of restenosis. Several reports showed a wide variability in the incidence of restenosis (between 3% and 70%) from one to three years of follow-up [19][20][21][22]25,30,31]. The rate of Rs in our study was 29.4% at 60 months follow-up, and was not associated with the presence of PAH.…”

“…However, in about one third of patients with mitral stenosis left ventricular systolic function is reduced. Preload reduction-caused by limited mitral inflow-and increased afterload-precipitated by reflex vasoconstriction secondary to decreased cardiac output, act in concert to reduce ejection performance [37,38]. We have demonstrated normalization of impaired LV systolic function after successful PMBV in patients with severe MS [38].…”

Percutaneous mitral balloon valvotomy (PMBV) was introduced in 1984 by Inoue who developed the procedure as a logical extension of surgical closed commissurotomy. Since then, PMBV has emerged as the treatment of choice for severe pliable rheumatic mitral stenosis (MS). With increasing experience and better selection of patient, the immediate results of the procedure have improved and the rate of complications declined. When the reported complications of PMBV are viewed in aggregate, complications occur at approximately the following rates: mortality (0-0.5%), cerebral accident (0.5-1%), mitral regurgitation (MR) requiring surgery (1.6-3%). These complication rates compare favorably to those reported after surgical commissurotomy. Several randomized trials reported similar hemodynamic results with PMBV and surgical commissurotomy. Restenosis after PMBV ranges from 4 to 70% depending on the patient selection, valve morphology, and duration of follow up. Restenosis was encountered in 21% of the author's series at mean follow-up 6 +/- 4.5 years and the 10 and 15 years restenosis-free survival rates were (70 +/- 3)% and (44 +/- 5)%, respectively, and were significantly higher for patients with favorable mitral morphology (85 +/- 3% and 65 +/- 6%), respectively (P < 0.0001). The 10 and 15 years event-free survival rates were (79 +/- 2)% and (43 +/- 9)% and were significantly higher for patients with favorable mitral morphology (88 +/- 2)% and (66 +/- 6)%, respectively (P < 0.0001). The effect of PMBV on severe pulmonary hypertension, concomitant severe tricuspid regurgitation, left ventricular function, left atrial size, and atrial fibrillation are addressed in this review. In addition, the application of PMBV in specific clinical situations such as in children, during pregnancy and for restenosis is discussed.

Restenosis after MBV range from 4% to 70% depending on the patient selection, valve morphology and duration of follow up. Restenosis was encountered in 17.5% of the author's series and the 10-year restenosis free survival is 68% and is higher (78%) in patients with favorable mitral morphology. The 10-year event free survival is 80% and is higher (86%) in patients with favorable mitral morphology. The effect of MBV on severe pulmonary hypertension, concomitant severe tricuspid regurgitation, left ventricular function, left atrial size and atrial fibrillation will be addressed in the review. In addition, the application of MBV in specific clinical situations such as children, during pregnancy and for restenosis is discussed.
